Too true! But, if the OP can get it done, it is _simple_ to do with a UNIX file. Just do an ftell() when you're process runs out of data in the file. Write than value into another file. The read that "checkpoint" file later; do an fseek() to the offset; then process from there. I think this is what the UNIX command "tail -f" does. Of course, in many cases, trying to convince z/OS people to use UNIX facilities rather than "legacy" facilities is like trying to get me want to use Windows <grin/>. Just not worth the time and effort. > > John Gilmore, Ashland, MA 01721 - USA -- There is nothing more pleasant than traveling and meeting new people!
